You should use another drug, in my country called a pipe tobacco
It is less harmful than cigarettes

Yes, I also know about waterpipe tobacco, can you share more about this drug
Is it a functional or somthing food?

It's also a type of cigarette but it's less toxic, no addictive and you can use it to forget cigarettes.

Well a good advice, I will learn about it more thoroughly, I also have problems with cigarettes

It is good to quit smoking because smoking can cause lung cancer and dehydration of the body. Smoking is no good for us, people.
